This issue is related to #3107 This is a first renaming/refactoring step before reworking and removing heartbeats. As discussed with @Liamsi , we preferred to go for a couple of independent and separate PRs to simplify review work. The changes: Help to clarify the relation between the validator and remote signer endpoints Differentiate between timeouts and deadlines Prepare to encapsulate networking related code behind RemoteSigner in the next PR My intention is to separate and encapsulate the "network related" code from the actual signer. SignerRemote ---(uses/contains)--> SignerValidatorEndpoint <--(connects to)--> SignerServiceEndpoint ---> SignerService (future.. not here yet but would like to decouple too) All reconnection/heartbeat/whatever code goes in the endpoints. Signer[Remote/Service] do not need to know about that. I agree Endpoint may not be the perfect name. I tried to find something "Go-ish" enough. It is a common name in go-kit, kubernetes, etc. Right now: SignerValidatorEndpoint: handles the listener contains SignerRemote Implements the PrivValidator interface connects and sets a connection object in a contained SignerRemote delegates PrivValidator some calls to SignerRemote which in turn uses the conn object that was set externally SignerRemote: Implements the PrivValidator interface read/writes from a connection object directly handles heartbeats SignerServiceEndpoint: Does most things in a single place delegates to a PrivValidator IIRC. * cleanup * Refactoring step 1 * Refactoring step 2 * move messages to another file * mark for future work / next steps * mark deprecated classes in docs * Fix linter problems * additional linter fixes

Package privval provides different implementations of the types.PrivValidator.
|
|
|
|
FilePV
|
|
|
|
FilePV is the simplest implementation and developer default. It uses one file for the private key and another to store state.
|
|
|
|
SignerValidatorEndpoint
|
|
|
|
SignerValidatorEndpoint establishes a connection to an external process, like a Key Management Server (KMS), using a socket.
|
|
SignerValidatorEndpoint listens for the external KMS process to dial in.
|
|
SignerValidatorEndpoint takes a listener, which determines the type of connection
|
|
(ie. encrypted over tcp, or unencrypted over unix).
|
|
|
|
SignerServiceEndpoint
|
|
|
|
SignerServiceEndpoint is a simple wrapper around a net.Conn. It's used by both IPCVal and TCPVal.
